Introduction

This introduction briefly describes Open ERP, its basic design, and its community. The rest of this wikipage details installing and configuring Open ERP on Arch Linux. It also provides additional information about Open ERP documentation, community, and development.

Open ERP features an application server which uses PostgreSQL for its database, along with a standalone GTK-based client, as well as a web-based client. It is written in the Python programming language, with a highly modular design which allows for the rapid development of new modules through Open Object RAD. Open ERP developers have a strong committment to free software.

A thriving support and development community has grown up around Open ERP, providing free technical support, bugfixing, new development, and support services. Open ERP provides extensive documentation in various electronic formats, as well as hardcopy. The company responsible for development of Open ERP earns profits through partnership services with Open ERP consultants, and by providing support, training, hosting services, software development, and software quality testing and verification.

Before Installing Open ERP

The following instructions assume that you have installed the 'sudo' command on your Arch Linux system. If you have not already done so, go to the sudo Arch Wikipage for more information.

Installing PostgreSQL

Open ERP uses the PostgreSQL database, which should be installed and configured before installing Open ERP. Follow the instructions in the "Installing PostgreSQL" section of the Arch PostgreSQL Wikipage. Complete these installation instructions, but do not perform any other configuration from that page. Return to this page for additional configuration steps.

Configuring PostgreSQL for local use on your own machine

If you plan to use PostgreSQL and Open ERP on the same machine, you will need to configure PostgreSQL to listen on the localhost's 5432 TCP port. Open /var/lib/postgres/data/postgresql.conf and navigate to the CONNECTIONS AND AUTHENTICATION section. Uncomment the listen_addresses and port lines. Save the file. When complete, the file should appear as follows:

Configuring PostgreSQL for remote use over a network

Setting up PostgreSQL to run with Open ERP

Next, it is necessary to create a new PostgreSQL user for Open ERP. In this example, the user is 'yourusername', but you should replace this with your Arch system login username. First, log in as the default PostgreSQL superuser, 'postgres', by executing the following command from the CLI:

sudo su - postgres

Once logged in as postgres, begin the process of creating the 'yourusername' user, with the folowing command:

createuser yourusername -P

You will first be asked for a password. For highly secure yet easy to remember passwords, consider using a Diceware Passphrase. Re-enter the password as requested. The next three questions should be answered in sequence with n, y, and n. Shall the new role be a superuser? n Shall the new role be allowed to create database? y Shall the new role be allowed to create more new roles? n

You may also use options as below to skip the interactive questions to set the attributes:

Once you are finished answering these questions, type the word 'exit' to log out from PostgreSQL as the postgres superuser.

You may want to edit your /etc/rc.conf file by adding postgresql to the Daemons list, so that PostgreSQL will automatically start up when you boot up your computer.

This completes the installation and setup of PostgreSQL for use with Open ERP under Arch Linux. Additional detailed information about PostgreSQL configuration may be found on the Arch Wikipage for PostgreSQL, and the PostgreSQL Manuals webpage. Also, there is a powerful GUI PostgreSQL Admin tool, pgAdmin, which is available in the Arch repositories.

Installing Open ERP from AUR

Open ERP requires the installation of the Open ERP Server, Open ERP comes with a webserver so you can use your web browser to use it. Currently, Open ERP is not available in the main repositories of Arch Linux, but it is available through the Arch User Repository.

use gunicorn to run openerp in multiple process

install gunicorn

yaourt -S gunicorn

write a python script

now you need to write a python script to run openerp. below is an example, you can change it for your needs. save it to your home directory and name it openerp-wsgi.py. for more information see gunicorn.conf.py
, note that the config file in /etc/openerp/openerp-server.conf has no effect to openerp if you use this script to start openerp.
